-LRB- CNN -RRB- -- American Airlines will cancel more flights from its daily schedule through mid-November .

`` American Airlines is extending its previously announced schedule reductions through the first half of November by approximately 1 % , '' said American spokesman Matt Miller in a statement . `` Although we are beginning to see improvements in our operations , we are taking this proactive step to allow us to get our performance back to the levels our customers deserve and expect . ''

The new cuts of about 31 flights per day out of the airline 's total network of 3,500 daily flights will not affect holiday travel , Miller said . Previously , the airline announced an up to 2 % reduction in the number of seat sales through the end of October .

The airline declared bankruptcy last year and has been mired in contract negotiations with unions . Airline executives convinced a bankruptcy judge to throw out the pilots ' contract last month .

In the past month , more than 1,000 American flights have been canceled and 12,000 delayed .

Some travel agents and business travelers have told CNN they ca n't count on American flights to take off or -- when they do take off , to land on time . Some American customers are starting to book flights on other airlines .

Airline management blamed the situation on pilots filing what it claims are frivolous reports about aircraft problems as part of a slowdown . The pilots ' union denied management 's assertion , arguing that company mismanagement has led to increased maintenance problems .

`` These mechanical items are all of American management 's making , '' American Airlines Capt. Carl Jackson , a representative of the Allied Pilots Association , told CNN on Thursday as several dozen American pilots conducted an informational picket at Washington 's Reagan National Airport .

`` They have old planes , '' Jackson said . `` They have a shortage of mechanics , here in the near term it 's going to be a severe shortage of mechanics , and we 're just trying to do the best we can to get the public safely to where they need to be . ''

The airline also faced questions about its maintenance after seats on three American Airlines flights have come loose in flight , requiring the airline to fix floor mounts in 48 of its 757s to prevent seats from coming loose again .

Although American management and pilots resumed negotiations last week , the three major American employee unions have already reached conditional agreement with US Airways , should a merger of the two airlines take place .
